It's funny how those people who are complaining about the last night's South Park episode and are calling for the show to be cancelled and those who used to complain about the lack of free speech and the prevalence of cancel culture are the same people.

I've got a suggestion to make democracies populist-proof.
Before any election, you need to pass and exam proving that you know how the thing you are voting on works.
It's free and you can take it as many times as you need to. But you aren't allowed to cast your vote until you pass this exam.

If you are a C# developer and want to get into machine learning and AI, you don't have to learn Python.

I am currently in the process of writing a book on it, which is available in early access.

Is any of you using static server-side rendering mode in #Blazor? If so, I'm curious to know the benefits of it.
To me, it doesn't seem to have any. Buttons don't work (unless it's something very simple), certain lifecycle events don't work, JavaScript interop doesn't work.

If you write software in .NET and build distributed applications, then you should definitely try .NET Aspire. This framework makes it so easy to develop and debug distributed apps. Nothing else comes even close.
We used it in our project at Microsoft. Things have become so much easier with it.
